Technical Field

[0001] This utility model relates to the field of vacuum insulation panel technology, and in particular to a seamless 3D vacuum insulation panel and insulation box. Background Technology

[0002] In cold chain transportation, insulated boxes are required for storage. To ensure good insulation performance, vacuum insulation panels are installed inside the insulated boxes. Vacuum insulation panels (VIP panels) are a type of vacuum insulation material. Due to their advantages such as low thermal conductivity, thin insulation layer thickness, small volume, good insulation performance, and good construction performance, they are widely used in home appliances, construction, and other fields, and have significant technical and economic value. Vacuum insulation panels effectively improve the insulation effect of insulated boxes.

[0003] In existing technologies, when vacuum insulation panels are used in insulated boxes, multiple independent vacuum insulation panels are usually attached to the inner wall of the insulated box to achieve the insulation effect. However, after attaching multiple independent vacuum insulation panels to the inner wall of the insulated box, there is a heat leakage problem between adjacent vacuum insulation panels, which affects the insulation effect of the insulated box. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, one objective of this application is to provide a seamless 3D vacuum insulation panel that, by setting a base core material and a surface core material, ensures that, due to the effect of the barrier film and the base core material, there is no problem of heat leakage at the folded position after folding, thereby improving the heat preservation effect of the insulation box.

[0005] The second objective of this application is to provide an insulated box.

[0006] The technical solution adopted by this application to solve its technical problem is: a seamless heat-leaking 3D vacuum insulation panel, comprising a lower barrier film, a base core material, a surface core material, and an upper barrier film; the base core material is disposed on the lower barrier film, the surface core material is composed of multiple pieces, the multiple pieces of surface core material are evenly disposed on the base core material, and a deformation groove is formed between two adjacent surface core materials; the upper barrier film is disposed on the surface core material, the inner edge of the upper barrier film is heat-sealed together with the inner edge of the lower barrier film, and an adhesive portion is formed on the outer edge of the upper barrier film.

[0007] Furthermore, the lower barrier film includes a first placement area and a second placement area, wherein the center line of the first placement area is perpendicular to the center line of the second placement area.

[0008] Furthermore, the first placement area and the second placement area are arranged in a T-shape.

[0009] Furthermore, the base core material includes a first core material and a second core material. The first core material is disposed on a first placement area, the second core material is integrally formed with the first core material, the second core material is disposed on a second placement area, and the second core material and the first core material are distributed in a T-shape.

[0010] Furthermore, adhesive tape is provided on the adhesive portion.

[0011] Furthermore, the tape includes a strip of tape disposed at the edge of the second placement area.

[0012] Furthermore, the first placement area and the second placement area are arranged in a cross shape.

[0013] Furthermore, the base core material is a glass fiber core material, and the surface core material is a glass fiber core material.

[0014] The technical solution adopted by this application to solve its technical problem is: an insulated box, including a box body, a box cover and the above-mentioned seamless heat-leaking 3D vacuum insulation board, the box cover is rotatably mounted on the box body, and the seamless heat-leaking 3D vacuum insulation board is attached to the inner side of the box body and the inner side of the box cover.

[0015] The beneficial effects of this application are as follows: During use, the lower barrier film, base core material, surface core material, and upper barrier film are stacked sequentially, and then a vacuum is applied. After vacuuming, the inner edges of the upper barrier film and the lower barrier film are heat-sealed together. Because the base core material is placed on the lower barrier film, there is no heat leakage problem at the folding position due to the action of the barrier film and the base core material. By setting multiple surface core materials, which are evenly distributed on the base core material, deformation grooves are formed between adjacent surface core materials. When folding is required, adjacent surface core materials are folded along the deformation grooves, making folding convenient. By providing adhesive parts, after folding, the adhesive parts at different positions are bonded together to form a box shape, making it easy to place inside the insulation box.

[0020] Explanation of reference numerals in the attached figures

[0021] Lower barrier film 1, first placement area 11, second placement area 12, base core material 2, first core material 21, second core material 22, surface core material 3, upper barrier film 4, deformation groove 5, adhesive part 6, adhesive tape 61, long strip adhesive tape 611. Detailed Implementation

[0022] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 As shown, this utility model discloses a seamless, heat-leaking 3D vacuum insulation panel, comprising a lower barrier film 1, a base core material 2, a surface core material 3, and an upper barrier film 4. The base core material 2 is disposed on the lower barrier film 1, and the surface core material 3 is composed of multiple pieces, which are evenly disposed on the base core material 2. A deformation groove 5 is formed between two adjacent surface core materials 3. The upper barrier film 4 is disposed on the surface core material 3, and the inner edge of the upper barrier film 4 is heat-sealed to the inner edge of the lower barrier film 1. An adhesive portion 6 is formed on the outer edge of the upper barrier film 4.

[0024] Thus, the seamless heat-leaking 3D vacuum insulation panel of this utility model is used by stacking the lower barrier film 1, the base core material 2, the surface core material 3, and the upper barrier film 4 together in sequence, followed by vacuuming. After vacuuming, the inner edge of the upper barrier film 4 is heat-sealed to the inner edge of the lower barrier film 1. Since the base core material 2 is placed on the lower barrier film 1, there is no heat leakage problem at the folding position due to the action of the barrier film and the base core material 2. By setting multiple surface core materials 3, and evenly distributing the multiple surface core materials 3 on the base core material 2, deformation grooves 5 are formed between adjacent surface core materials 3. When folding is required, the adjacent surface core materials 3 are folded along the deformation grooves 5, making folding convenient. By setting adhesive parts 6, after folding, the adhesive parts 6 at different positions are bonded together to form a box shape, which is convenient for placement inside the insulation box.

[0025] Optionally, the lower barrier membrane 1 includes a first placement area 11 and a second placement area 12, with the center line of the first placement area 11 and the center line of the second placement area 12 perpendicular to each other. The first placement area 11 has three placement positions for placing three surface core materials 3, and the second placement area 12 also has three placement positions for placing three surface core materials 3. Thus, a total of six surface core materials 3 are provided, corresponding to the six panels of the insulation box body and lid, enabling the insulation box to have good insulation performance.

[0026] In this embodiment, the first placement area 11 and the second placement area 12 are arranged in a T-shape. The base core material 2 includes a first core material 21 and a second core material 22. The first core material 21 is disposed on the first placement area 11, and the second core material 22 is integrally formed with the first core material 21. The second core material 22 is disposed on the second placement area 12, and the second core material 22 and the first core material 21 are arranged in a T-shape. Because the first placement area 11 and the second placement area 12 are arranged in a T-shape, it is convenient to cut the upper barrier film 4 and the lower barrier film 1.

[0027] To facilitate the secure bonding of adjacent edges after folding the seamless, heat-leaking 3D vacuum insulation panel, adhesive tape 61 is provided on the bonding portion 6. Specifically, in the seamless, heat-leaking 3D vacuum insulation panel where the first placement area 11 and the second placement area 12 are arranged in a T-shape, the adhesive tape 61 includes a long strip of adhesive tape 611 positioned at the edge of the second placement area 12, thereby facilitating the fixing of the long strip of adhesive tape 611 at the edge position.

[0028] Of course, in other embodiments, such as Figure 4 As shown, the first placement area 11 and the second placement area 12 can also be arranged in a cross shape as needed.

[0029] Furthermore, the base core material 2 is made of glass fiber, and the surface core material 3 is made of glass fiber, which makes the thermal conductivity of the seamless heat-leaking 3D vacuum insulation panel low.

[0030] This utility model also discloses an insulated box, including a box body, a box lid, and the aforementioned seamless heat-dissipating 3D vacuum insulation panel. The box lid is rotatably mounted on the box body, and the seamless heat-dissipating 3D vacuum insulation panel is fitted onto the inner side of the box body and the inner side of the box lid. In use, after the seamless heat-dissipating 3D vacuum insulation panel is fitted onto the inner side of the box body and the inner side of the box lid, the insulated box achieves excellent heat preservation.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
